"I'm a Minor, I'm Arrogant" revolves around the protagonist Mo Xie (Ah Xie), telling the story of his struggle, degradation and resistance in the darkness.
Axie was born in the Shadow District of the Sea City of the Oriath Federation, where poverty, violence and crime are rampant, and the law is difficult to reach. His family is full of misfortune. His father Wang Daqiang is an alcoholic and gambler, and his mother Lin Fang is addicted to drugs under long-term torture. Ah Xie was beaten and scolded by his parents in his childhood. When he was five years old, his mother sold him to a trafficker. Although he escaped, he has been living on the streets ever since.
During his wandering life, Ah Xie suffered a lot of bullying. He often competed with stray cats and dogs for food, and was also bullied by other street children. When he was seven years old, he discovered a chemistry book in the basement of an abandoned factory. With his talent, he began to make poisons and embarked on the path of crime. As he grew up, the hatred in Ah Xie's heart became stronger. With the tenacity he had developed through suffering and the poison knowledge he had mastered, he decided to take revenge on those who had harmed him. At the same time, he also tried hard to find his own way of survival in this dark world. As a minor, he "arrogantly" carved a bloody path in the cruel reality.
